If you do 27-12 (which is 15) you add 15 to 13 and 20
Answer:
the mean of a set is the average of the numbers in that set. How you get the mean is you add up all the numbers then you divide by how many numbers are in the set.
Step-by-step explanation:
example is 1,2,3,4,5,6,7
the mean of this set is 4
4(2x+1) = 3(x+8)
8x + 4 = 3x + 24
5x = 20
∴x = 4
Answer:
a=k1![\sqrt[3]{B}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7BB%7D)
B=125
Step-by-step explanation:
Given :
a=3
B=64
According to question
a ∝ ![\sqrt[3]{B}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7BB%7D)
therefore
a=k1
........Eq(1)
K1=
......Eq(2)
Putting the value of a and B we get in Eq(2) we get

Putting the value of k1 in Eq(1)
.......................Eq(3)
putting the value of a=15/4 IN Eq(3) we get
![\frac{15}{4}\ =\frac{3}{4} \sqrt[3]{B} \\\\\sqrt[3]{B}\ =\ 5\\Cubing\ both\ side\ we\ get\\B=125](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B4%7D%5C%20%3D%5Cfrac%7B3%7D%7B4%7D%20%5Csqrt%5B3%5D%7BB%7D%20%20%5C%5C%5C%5C%5Csqrt%5B3%5D%7BB%7D%5C%20%3D%5C%205%5C%5CCubing%5C%20%20both%5C%20%20side%5C%20%20we%5C%20%20get%5C%5CB%3D125)
